Be it known that I, JAconL.` Jncops, 4a citizen ofthe United States, `and resldent of the city-of New York, borough of Mau-` hattan, in the county1 and State of New York, have invented a new `and Improved is a full, clear, and exact description.`

In connection withstampingand more particularly stamping ribbons, itiis well appreciated that it has been customary-to;` util-` ize what is known asthe gold leaf` processff s to the same .will befproperly placedupon to obtain a deinite` impression upon the ribbon. i f t The gold leaf process, `as is well known, involves the expenditure of considerable time and material `toproperly practice the same.

i It `has often been `attemptedto gold in liquid form (gold ink) to a ribbombut this has been heretofore unsuccessfulin view of thefact that the impression would not.

last, and was not clearcut@ l v i It will readily be funderstood,'however,

Ithat if the use` of ink, lgoifrieaf @liquid were practical, that `this wouldbe themost desirable molde ofapplyingmarks toribbons in view of the saving of time involved, as well as the reduction ofexpense and mate-` rials utilized. t i .y 1. 1

With this in view, I have constructed a machine, and more particularly a stamping machine, by means of` which gold (liquid` or ink) may be used in applyingmarks to ribbons, and which will reproduce the mark in a clear cut impression,fwh1ch ma be i subjected to extremely rough usage wit `out detrimental effects. i 1 It is also well understood,thatqdiliiculty has been experienced in` properly `holding a length of ribbon so that `a mark applic the body of the ribbon with a Viewofipro-` ducing` work which" shall beneat 1n appearance.` i c With this latter defect mind, have constructed a machine which,` in` addition to permitting ofthe utilizingoffliquid gold for applying marks to ribbons, shall further incorporate, as apart ofits structure,cer`

tain means permitting ofthe proper holding and guiding of a ribbon, whereby `tolinsure 'l jSpeciiicatonof Letters atent. i

aperfect alinement ofthe mark placed upon i the Same.`

tothe attached sheets `of drawings as illustrating `:one practical embodiment` or' my invention, and in which In these: views the reference numeral 10 .indicates the bed plate, to which a standard' 11 is secured, said standard supporting a machine,` conforming `in its `major aspects to` the conventional hand printing press in thatlspring pressed inkingvrollers 12 `are caused to travel over guide rails 13 by means rollers traveling over their upper limit of motion, and passing over` and applying ink to the die uponmov` ing `totheir most retracted position.

. The conventional platen 16 cooperates withthevdie, and when the rollers 12 have been moved upwardly `by means of the handle forward so as to contactwith thedie. 1

Referringnow more particularly tothe die restingin the bed of the press it will be seeirtliat the same conventional `irame 17 in which the die 18 is positioned `and held by means of any suit able `securing means blocks Contrary to the usual conventional construction heating members formed by rheostatstrips 2G are introduced between the side `walls of the die 1S `and the blocks 19, such rheostat including an incasing member and a conventional resistance wire, to the ends otwhich terminals `21 are connccted. 1

i A source foil" current connects with the wire 22, `the endportions of whicharc connected tothe terminals 21 so that the strips 20 are inl series. By this arrangement `it willbe appreciated that the die 18 will be the platen in the usual manner is moved conveniently includes a such as wedges and heated to a high temperature, and that the same may be removed and substituted for anydie, by loosening the wedges 19.

Referring now to the platen A16, itwill be Lseen that when the ribbon 23 upon which an imprint is to be made isufed across the face oi' the same at a position 'in line with the die y, 18, that the platen is brought flush against the 'a-ce of the latter. y

Now with a view oi' providing means which will properly 'guide andretain the ribbon during the workingstroke of the' machine, a pair of strips 24: lie vacross the aceofi'the platem'andhave their outer ends hingedly secured as at 25 to the upper" edge oiftlie platen 16.

the ends26 of the strips '24' and the bedl()V of the machine, any suitable adjusting" mea'ns'suchasbolts 28 being providedfor regulating `the tension of theV springs. Y

,ltfwill new be uiiderstood, that the ribbon L 23 lyingacrossthe face of the platen'upnn the striking "surface ,29 secured toA the" saine will be'normallypermitted to move freely" with respect to the platen by virtueofthe iact that the springsV 2TV are adjusted with such nicety as to. insure the taking up of'all ofv thetension prior tothe platen' reaching itsextreme, .outer position, soA that the springswill 'act as a bufler to rock the outer ends 'of thestripsaway from theifa'ce ofthe platen. KI-lowejver, upon the platen swinging upwardlyie. moving to pointat which the jstrikin'g surface .29 bears against the face-.ofthe die .18', ther strips '24kV will swing" ushagainstthefupper face'of .the platen',`

whereby to clamp the'ribbon inifposition. This actionY willbe accomplished by virtue of theffactthat one end of the 'strips 24is secure'dto. animmovable portion or" the machine, tof wit,the plate 10; a yieldingconnectionbeing :turnishedbetween these portions by virtue of the springs 27.

The'guiding means conveniently embraces `a vplate 30 formed Vwith a slot 31 through which the Yribbon 23 passes, the same being subsequently .introduced into the adjustable guiding members 32, whence it passes across the striking surface 29, and under the strips 24 arranged to each side of the same, subsequently emerging through a second pair of adjustable guide members 32, and a receiving platform In operation it will now be understood,

` that it will only be necessary to apply liquid gold orink to the turn table 15 formed in the lnlzing bed, and to applythe die to Athe jbed of the press, current being introduced into vthe rheostat strips 20.to insure l j a'high heating ofthe die 18. The ribbon '23' will now be passed through the slot 31 and the adjustable guide members 32 will be opened to permit ot the insertion ot the ribbon between their bodies and the upper face ot' the platen 1G, the ribbon thence passing under the strips 21 and over the striking surface 29 and so on to the platform 33'.

LA movement on the part oi" the handle will novcause the platen to bear against the. die,I the inking rollers 12 in the usual manner passing upwardly on to the inlri'ng bed. A retrograde 'movement on the part ot the handle will open the press and permit an application of inleto the die 1S, by means of theinlring rollers 12. lt will `be noted thatas the'plat'en moves` upwardly the ribbon is h'eld from movement by virtue of the strips 24.- ywhich clamp the said ribbon bctw'een' their under faces, and the upper lare off the platen, thus preventing any movement an'd'a'ccord'ingly blurred marking on the Jp'art'of the ribbon. j

It 'will'also be 'understood 'that by virtue oi' thisarrangement that the ribbon may be left inonepositioinand be. applicd'tt') the die av number ot times without fear of blurred marking in the event that one inipression does lnot givev the desired result. Also'by rcasonof th'c guide members, the ribbon .will 'at all times be properly icd over the striking surface 29 so that the impression upon the ribbon will be properlv placed.V

Obviously numerous modificationsv of structuremight be resorted to without in the leastK departing'from the scope ot mv claims, which read as follows.

That I claiuras'new is 1 1. stamping'machine, including a bed, a'diewithinlsaid bed, a platen, means for movingsaid' platen 'into 'and out of contact Witli'said"d'ie,means upon said platen for guiding a ribbon across its face, and means for clamping saidA ribbon against movement "with respect tosai'd'platen', upon Isaid pl'ateiifbeing moved toward said die.
